Lavabelly Sliver

Most Sliver lords add a keyword or a stat bump that stacks across the board; this one changes the winning axis from combat to attrition. Because the granted trigger goes to every Sliver you control (including this one), each subsequent arrival pecks an opponent for one and tops you off a life at a time, and the tribe's usual game plan (flood the board, then overwhelm) becomes a drain engine instead of an attack step. A modest board dump starts chipping away immediately, and those pings multiply as each new body enters and drains again. The color pairing is the tell: red-white is where go-wide aggression that closes out of nowhere tends to live, and here the closer is the sum of enter-the-battlefield triggers, which routes damage around blockers and after-the-fact sweepers entirely. It also quietly answers a longstanding Sliver weakness, the deck's difficulty grinding through a stalled board, by turning each replacement threat into direct reach. The target line reinforces the point: it hits players or planeswalkers, so a wide Sliver board can dismantle a superfriends plan one arrival at a time. On its own the 2/2 frame is unremarkable, but as the drain payoff the tribe had circled for years without a clean printing, it does the work no combat-keyword lord ever could.
